WiFi Test Engineer

Celona; Bengaluru; On-site; INR 900,000 - 1,300,000; Full time

Job summary

Celona, a leader in private 5G and enterprise wireless, is seeking a WiFi Test Engineer to join the QA team in Bengaluru. You will design and execute test plans for Wi‑Fi and private cellular coexistence, build benchmarks, and automate regression suites with Python while integrating with CI.

You will set up lab environments, triage failures across RF, MAC, IP and applications, and collaborate with product and systems engineering to ensure release readiness. 4+ years in wireless test is required.

Qualifications

• 4+ years in wireless test, QA, or network engineering.
• Deep 802.11 knowledge: a/b/g/n/ac/ax; roaming, WPA2/WPA3, DFS, channel planning.
• Hands-on with Wireshark, iPerf, Ixia/Spirent or similar, spectrum analysis tools.
• Python scripting and test automation experience.
• Comfortable reading specs and turning them into test cases.

Responsibilities

• Design and execute test plans for Wi‑Fi/private‑cellular coexistence, interoperability, and handoff scenarios.
• Build comparative benchmarks (throughput, latency, jitter, roaming behavior, client density) between Wi‑Fi and Celona deployments.
• Set up and maintain lab environments: APs, controllers, spectrum analyzers, traffic generators, RF chambers, attenuator matrices.
• Automate regression and performance suites in Python; integrate with CI.
• Triage failures across the stack — RF, 802.11 MAC, IP, application — and file actionable defects with captures and logs.
• Validate client behavior across Windows, macOS, iOS, Android, and industrial IoT endpoints.
• Support field trials and customer escalations with reproducible lab repros.
• Partner with product and systems engineering on requirements and release readiness.

Job description

Celona has led the evolution of private 5G from an emerging technology to critical infrastructure across some of the world's most demanding industries and environments. Celona is now defining a new category of enterprise wireless purpose-built for physical and agentic AI - converging private 5G, Wi-Fi, public cellular, and satellite into a unified wireless fabric with agentic intelligence built in.

The result is a deterministic wireless foundation purpose-built for the AI-native enterprise, connecting AI agents, autonomous machines, and the people who work alongside them.

Celona is seeking a WiFi Test Engineer reporting to Celona's Director of QA Engineering.

Requirements

• Design and execute test plans for Wi‑Fi/private‑cellular coexistence, interoperability, and handoff scenarios
• Build comparative benchmarks (throughput, latency, jitter, roaming behavior, client density) between Wi‑Fi and Celona deployments
• Set up and maintain lab environments: APs, controllers, spectrum analyzers, traffic generators, RF chambers, attenuator matrices

• Support field trials and customer escalations with reproducible lab repros
• Partner with product and systems engineering on requirements and release readiness

What you'll bring

• 4+ years in wireless test, QA, or network engineering
• Deep 802.11 knowledge: a/b/g/n/ac/ax (Wi‑Fi 6/6E), and ideally 7; roaming (802.11r/k/v), WPA2/WPA3, DFS, channel planning
• Hands‑on with Wireshark, iPerf, Ixia/Spirent or similar, spectrum analysis tools
• Python scripting and test automation experience
• Comfortable reading specs and turning them into test cases

Nice to have

• Exposure to LTE/5G, CBRS, or spectrum-sharing (SAS) concepts
• Experience with enterprise Wi‑Fi platforms (Cisco, Aruba, Mist, Ruckus)
• CWNA/CWAP or equivalent
• Prior work in manufacturing, logistics, healthcare, or education networks
